Wind Energy Information. From offshore wind turbines to understanding wind turbulence, learn all about using the wind to our advantage. Also, wind testing buildings.
On the runway to more fuel-efficient aircraft, one alternative propulsion scheme being explored is an array of electrically powered ducted fans. The fans are distributed across the wing span or integrated into the wing. Researchers have gained new understanding in how the fans and especially their precise placement on the aircraft can affect the cross-conversation between propulsion and the airflow around the wing.

Depending on how wind turbines are situated relative to each other and to the prevailing wind, those not directly in the path of the wind could be left to extract energy from significantly depleted airflow. However, according to researchers, there are ways to get around this issue of diminishing wind returns.

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. Researchers report the most accurate modelling yet of how increasing wind power would affect climate, finding that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius because wind turbines redistribute heat in the atmosphere.

Scientists know that upward currents of warm air assist birds in flight. To understand how birds find and navigate these thermal plumes, researchers used reinforcement learning to train gliders to autonomously navigate atmospheric thermals. The research highlights the role of vertical wind accelerations and roll-wise torques as viable biological cues for soaring birds. The findings also provide a navigational strategy that directly applies to the development of UAVs.

Wind and solar farms are known to have local effects on heat, humidity and other factors that may be beneficial -- or detrimental -- to the regions in which they are situated. A new climate-modeling study finds that a massive wind and solar installation in the Sahara Desert and neighboring Sahel would increase local temperature, precipitation and vegetation. Overall, the researchers report, the effects would likely benefit the region.

Engineers are developing a cooled, radial gas turbine for a small generator that provides thousands of hours of electricity to an unmanned aerial vehicle (UAV), a significant improvement to current UAV turbines that only operate a few hundred hours before wearing out.

Hawaii is famously reliant on imported fossil fuels, for both electricity and transportation. But that’s changing rapidly as the state invests heavily in renewables. Two new bills are now pending in the Hawaii legislature that would codify the 100 percent renewables goal statewide, up from the current mandate of 40 percent by 2030. HB 623 would require...

In the ongoing wars over solar energy, one power company is consistently painted as the archetypal, mustache-twirling nemesis of clean electricity: Arizona Public Service. So you might be surprised to learn that this same company is about to become a big new producer of rooftop solar power. APS is an unlikely solar patron: In the...

Home solar batteries from Tesla Motors, which could upset utilities as we know them. Billion dollar solar bonds from SolarCity, backstopped by banking bigshots. Happy Earth Day! After being artificially suppressed for decades, renewable energy developments have accelerated, with excellent timing. Earth Day brought mounting news via Bloomberg that Tesla’s anticipated home solar batteries, hinted at in March...

This story is excerpted and adapted from Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future, due out May 19 from Ecco, an imprint of HarperCollins. On May 8, 2013, Tesla Motors shocked just about everyone by posting its first-ever quarterly profit, reporting higher-than-expected demand for its Model S electric sedan. That moment marked the beginning...
